hello colleagues
test mosfet specification
there is big problem becam famous now many bad new mosfet in the market
for example IRFP460A it.s Characteristics is Drain to Source Voltage
is 500v and Drain Current is 20A BUT WHEN I BOUGHT 4 transistors in akai plasma
burned SO FAST AND DAMAGE DRIVER IC.S AND POWER SUPPLY UNIT
AFTER REBUILD GET OLD 4 TR IRFP460A
TV WORKS GOOD many colleagues KNOW THAT (especially TR POWER AND MOSFET)
have not the same specification which in data sheet( original not exist in most cases )
so i Need any tools to measure drain current and Drain to Source Voltage....etc
to make sure it is good before i put it in the set
test circuit which exist in some data sheet not useful
any body have idea document or tools for seal to do this to avoid big damage please help with any info
kind/regards
